You can definitley tell they have n idea because Slash could never be compared to Richie! Van Halen yeah, I mean the guy changed the way the guitar was played but SLASH!, come off it! He did some great riffs but live he always ****s up, sounds like a drowning cat! I don't think it's that Richies underated but that he's never really done much for the guitar world. He's a class rock guitarrist but has never invented a new style but followed on guitarrists like Page, Clapton...
